PURPOSE: The purpose of this study is: 1) To determine which warm-up technique (general warm-up (GW), dynamic warm-up (DW), weighted vest warm-up using body weight percentage [VW], and elastic exercise band training system warm-up [EEBTSW]) will provide the best and longest effect on athletes’ performance regarding power output, agility, and flexibility. 2) To compare if there are any differences in power output, agility, and flexibility when using different resistance protocols (VW and EEBTSW) as warm-up techniques. 3) To determine which warm-up will benefit the athletes’ performance. 4) To compare the hemodynamic responses to different warm-up techniques.
METHODS: Thirty-one male (age= 21.93 (2.71) n=15) and female (age= 21.25 (1.77), n=16) athletes performed four different type of warm-up on for separate occasions separate by at least 48 hours. Each of the sessions were randomized into the following conditions: GW (Control), DW, VW, and EEBTSW. During each warm-up, heart rate (HR), blood pressure (BP), and rate of perceived exertion (RPE) were recorded throughout the study. After the warm-up, flexibility, counter movement jump (CMJ), and T-test were performed. Flexibility and CMJ were tested every 2,6,10, 14, and 18 minutes, and T-test was tested every 2, 10, and 18 minutes.
RESULTS: There were significant condition*time interactions for HR, BP, and RPE (p<0.01) and significant condition and time main effects (p<0.01). No significant difference was found between conditions for flexibility, but there was a significant time difference (p<0.01). Both VW and EEBTSW were significantly better than GW at two and six minutes post warm-up for power. At ten minutes post warm-up, EEBTSW was vi significantly better in power than DW. EEBTSW and VW was significantly better than GW for agility at two-minute mark (p<0.01).
CONCLUSION: The findings showed that the effects of both EEBTSW and VW on power lasted for six minutes compared to GW. In addition, both resistance warm-up techniques resulted in a better agility performance at two-minute mark following warmup. This suggests that using resistance warm-ups would be ideal for those individuals, who perform activities requiring high levels of power and agility.
